expand (x^2y-1)dx+(x^2+y^2)dy

expand

(x^{2} y - 1) d x + (x^{2} + y^{2}) d y

x^{2} y d x - d x + x^{2} d y + y^{2} d y

Solution steps

(x^{2} y - 1) d x + (x^{2} + y^{2}) d y

Expand

d x (x^{2} y - 1) : x^{2} y d x - d x

= x^{2} y d x - d x + (x^{2} + y^{2}) d y

Expand

d y (x^{2} + y^{2}) : x^{2} d y + y^{2} d y

= x^{2} y d x - d x + x^{2} d y + y^{2} d y

(x^{2} y + 2 x^{5} y) d x

\frac{12 - 4 m}{3 ( 5 - m )}

4 - 6 (2 (2) + 1 = 10)

(w - 7) (w + 5)^{'}

y^{2} sin (x) d x (2 + 3 y) d y
